PENCIL.

SPECIFICATION forming part of Letters Patent No. 384,383, dated June 12, 1888.

Application filed September 14, 1887. Serial No. 249.690. (No model.)

To aZZ whom it may concern.-

Be it known that I, LEWIS B. MYERS, a citizen of the United States, residing at Fremont, in the county of Sandnsky and State of Ohio, haveinvented certain new and useful Improvements in Pencils; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to pencils.

The object is to produce a pencil which, whilebeing constructed ofa comparatively few number of parts, will at the same time be efficient and reliable in use and inexpensive to manufacture.

Heretofore in pencils ithas been customary to make the clamping-jaws and crayon-tube in one piece. In the present invention the clamping -jaw is separate and distinct from the crayon-tube, the handle of the pencil forming the receptacle for the lead or crayon and having the clampingjaws attached thereto.

"With these objects i n view my invention consists in a tube or handle, to an end of which is attached a clamping tube having one end formed into a sleeve designed to tit upon the tube or holder, the other end being slitted longitudinally in order to receive and clamp the lead or crayon placed therein.

Furthermore, the invention consists in a clamping sleeve placed over the clampingtube, the upper end of which is designed to fitand slide upon the shoulder formed by the sleeve of the clamping-tube, its lower end be ing contractedin orderto close the slitted jaws.

Furthermore, the invention consists in a coiled spring fitted loosely on the slitted portion of the clampingtube, said spring being designed to push the clamping-sleeve in the direction required to close the slitted jaws.

Furthermore, the invention consists in a tube attached to the handle on the end opposite that on which the crayon-holder is placed, one end of which is secured to the handle, the opposite end being left open for the reception of a rubber eraser.

Furthermore, the invention consists in a movable sleeve designed to fit and slide upon the tube.

Furthermore, the invention consists in a coiled spring placed within this tube and designed to keep the sliding sleeve in position over the rubber; and, finally, the invention consists in various novel details of construc tion, hereinafter fully set forth.

In the accompanying drawing, forming part of this specification, and in which like letters of reference indicate corresponding parts, the figure is a vertical sectional view'o'f my invention, showing at one end the clampingtube, the coiled spring, and the clampingslecve, and at the other end the stationary tube, the sliding sleeve, and the coiled sprin Referring to the drawing, A represents a tube or handle designed to contain lead, crayon, or rubber, and having at one end a clamping-tube, a, the upper end of which is formed into a sleeve, a, designed to fit on the end of the holder, the lower end being slitted longitudinally to form the clainpingjaws a said jaws being constructed to clamp and hold firmly the lead or crayon placed between them.

A clampingsleeve, B, is placed over the clamping-tube, is held in place by and takes its bearing on the shoulder a", and is so arrangedthatit mayslidelongitudinallythereon, its forward movement being limited by the bulbs a, formed on the ends of the clampingjaws, and its rearward movement by the shoulder 1) of the clainpingslecvc.

In order that the clamping'slecve may be pushed upon the clamping-tube and thus close the jaws upon the lead, crayon, or rubber, a coiled spring, 0, is placed loosely upon the jaws and is held in position by the shoulders a and Z).

The sleeve B is tapered toward one end, Z), which surrounds the clamping-jaws, and closes them when the sleeve is pushed in the proper direction by coming in contact with the bulbs on the ends of these jaws, thus causing them to grasp and hold firmly the lead, crayon, or rubber placed in them.

Attached to the handle, atihe end opposite that to which the clamping device is secured, is a tube, D, one end of which is left open for the reception of a rubber eraser. Fitting loosely over this tube is a sleeve, (1, which is held in position against slipping off by the pin d,which passes through the sleeve and is riveted on both sides.

Within the tube D is a coiled spring, d, which serves to push the sleeve (1 out over the rubber, and thus protect it from becoming soiled. In order to accomplish this result, the tube D is provided on two sides with longitudinal slots (1, through which passes the pin (1, and against which the coiled spring rests. It will readily be seen that if the sleeve be pushed back the spring will be compressed by means of the pin, and that when the pressure is removed it will instantly resume the position requisite for the accomplishment of the object for which it is designed.

If desirable, the pin may be secured in the movable sleeve by means of slight inner countersinks, into which its ends are inserted, thus leaving the pin unexposed and presenting a neater and better finish on the outside.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The tube having thelongitudinal slit extending for a suitable distance of its length, with a clamping-jaw fitting on the open end and provided with an annular shoulder, in 25 combination with asleeve fitted on said clan1ping-jaw and having converging ends bearing thereon, and also provided with a shoulder and a coiled spring placed around the clampingjaw and bearing against the shoulders of 30 the clamping-jaw and sleeve, respectively, for the purpose set forth.

.2. The combination, with the closed end of the pencil, of an open tube fitted thereon and provided with a slot, and asliding sleeve fitted on said tube and provided with apin working in said slot, which pin divides the stationary tubeinto two compartments to receive aspring and eraser, the spring bearing against the closed end of the pencil and the pin, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
